CORDING ATTACHMENT FOR SEWlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 223,364, dated January 6, 1880.

Application filed February 24, 1879.

To all whom it may concern Be it known that I, ALONZO LOBDELL, of Racine, in the county of Racine and State of Wisconsin, have invented a new and useful (lording Attachment for Sewing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to a cording attachmentfor sewing-machines; and it consists in devices, substantially as described, for holding the strip that is to cover the cord folded centrally and closely over the cord as it passes to the needle.

In the drawings, Figure 1 shows the holder or guide for the cord and its covering-strip in proper position relative to the presser-foot and needle, as the same will appear when secured to a machine. Fig.2 is a sectional view of the guide, showing the relation of the same to the several parts or fabrics to be joined. Fig. 3 is a top view of the presser-foot, and Fig. 4 is a centralvertical section of the same.

A is a strip of metal, bent backward near itsend to form a groove or passage, a. B is a second strip, of the same width, provided at one "end with the lips b b and tongue t. These lips and tongue are preferably formed by clasping a third and shorter strip, 0, over the end of strip B and bending its ends for- Ward, as shown, to form the equal grooves c 0, one on either side of the tongue. These twin grooves or passages may, however, be otherwise formed from the strip B, made of sutficicnt length for this purpose.

Both strips A and B are centrally and longitudinally slotted at s"to receive the setscrew S, by which they are adjustably held together, and also held in proper position upon the bed-plate of the machine and before the needle.

The loop L assists in holding the parts A and. B in proper lateral relation, and serves especially to prevent the separation of these parts when the apparatus is detached from the machine.

The object of that portion of the attachment composed of the parts described is to guide the cord I and to hold the covering-strip H evenly and closely folded about the cord as it is advanced to the needle. For this purpose the rising wall of the passage to is regularly curved to conform with the cord and its covering, which are together passed through the same, as shown clearly in Fig. 2. The edges of the covering-strip H lie in the grooves c c, the width of the strip being such that the edges will strike the bottom of the grooves when the tongue is made to bear against the cord. The parts D and E of cloth or other material to be seamed are placed one above and one beneath the guiding device, as also shown in Fig. 2, and are preferably directed wholly by the hands, their edges being readily brought into line with the edges of the cordcovering strip H.

In connection with the holder and guide described, I use apresser-t'oot, F, having a groove, G, in its bearing face, which rides astride the ridge produced by the cord. It also has a horizontal bearing, 1', which holds the several thicknesses in contact at their edges and near the needle or. The groove G, bearin g on both sides of the cord-ridge, secures uniformity in the distance between the cord and the seam throughout their length, and gives perfect evenness in the protrusion of the cord when the seam is turned.

My improved attachment is more especially intended for heavy cording, such as is done in the manufacture of carriages, cushions, upholstery,&c., which has hitherto been done by hand.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination of the part A, having its end bent to form the cord-passage a, and the part B, provided with the tongue t, and the part 0, with the double-fold lips b 11, forming the grooves c a, substantially as and for the purposes specified.

2. The part A, curved at its end to form the cord-passage a, combined with the adjustable part B, provided at its forward end with the double-fold piece 0, forming the bindingguide,

adjustable with said piece 13 forward and backward within the curved end of part A, and the set-screw S, whereby said adjustment is secured and the implement is attached to the sewing-m achine, substantially as set forth.

3. A guide for the cord and covering-strip, composed of a part, A, the end whereof is 'folded back upon itself, with a proper curve and suffieiel'lt space intervening, combined IO with a part, B, folded upon itself twice in the form of the letter \N and inserted within the fold of the part A in the manner set forth.

In testimony that 1 claim the foregoing as my invention I affix my signature in presence of two Witnesses.

ALONZO LOBDELL.
